Anyone seen any of the 458's available or know when they are to be available? Thanks.

A lot of looks, but no replies yet, so I will offer a suggestion. Try Gallery of Guns on the web. They usually have listed what is available and a price. You might also have your friendly dealer call some of the big wholesalers, Williams, RSR, Ellett Brothers, and the like and see if they can give them any sort of information as to delivery.
It might be that a lot of dealers, in this time of a not so good economy, are reluctant to stock an item that is that specialized. They may be able to order one now. Good luck!

I have heard of 375's being available and personally seen a few 416's on the shelf. 458's could not be far behind.

EZ

They are coming, my guess is soon. My dealer has several 375s and I bought one of two 416s, love it.

I bought a .375. Posted a report a couple days ago.

Thanks fellas.
I did call the Winchester Customer Service folks today. They didn't give me a specific date of shipment. However, they did tell me that the 458's would be shipped "next month".
Lets hope this means September.
Regards to all who responded.

It seams Like everbody has one. Myself I have the American Safari 500 458 Lott.

The 375s are definitely available. I just bought one about 4 weeks ago.

I handled the Win. .375 today, alongside a Ruger 77 in .416. Of course, the Ruger is a bit heavier, but the Winchester was much livelier in my hands. Very tempted!
